The bump is for water jacket clearance through that area just behind the valve guide boss. Be real careful in that area, just blend it into the roof of the port, do not remove any material than needed.

This is a link to what its gonna look like www.dbtech.net/barb/portsculptor/ it will be up at the end of the week...hopefully with a dyno graph of a stock 98 M6 Formula that picked up over 7 hp/tq on a TB. This is just the main page with my TBs on it and will have cylinder head pages behind it.
